TWISTING AND WINDING APPARATUS.

Application filed May 19, 1923, Serial No. 640,110. Renewed November 6, 1925.

This invention relates to twisting and winding apparatus 01" that general type illustrated in my Patent No. 1,258,412, March 5, 191.8, and which comprises a to tatable yarn container and a winding head tor laydng the yarn under pressure in said yarn container in loops forming layers er;- tending at right angles to the axis of rotation, the apparatus being usually arranged so that it will twist the yarn before it is delivered to the winding head.

In machines oi this type the yarn re ceiver is supported on a vertically-movable step bearing so that it can be raised into operative relation to the winding head :for the tn". ing and winding operation and can be lowered to permit it to be removed from the winding head for the purpose of removing the yarn mass accumulated therein.

One of the objects of my present inven tion is to provide a novel means for thus raising or lowering the yarn containers.

.Another object of the invention is to provide a novel means for locking and holding the yarn containers in their raised or operative position so that they will be retained in such position.

Still another object of the invention is to provide a novel interlocli ing connection between the means for raising the yarn containers and the devices for controlling the operation of the machine so that the machine cannot be started until the yarn containers are all raised and in their operative position. and the yarn containers cannot be unlocked and lowered while the machine is running and until alter the belt shipper or other control mechanism for the machine has been operated to bring the machine to re" he purpose of this is to prevent the p Jility oi? the machine being operated when any of the yarn containers are in their inoperative position.

The invention has various other novel features all as will be more fully hereinafter set forth.

in. order to give an understanding of the ii'ivention l have illustrated in the drawings selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended cla ms.

Figs. 8 and 9 illustrate the belt shipper and a portion of the interlocking connec tion between the latter and the device for controlling the vertical movement oi the yarn containers.

Figs. 10 and 11 illustrate an interlocking connection between the belt shipper and the shaft 36.

As stated above the machine herein illustrated is oi that type which comprises a plurality of yarn containers each rotatable about a vertical axis and winding heads tor winding tlieyarn in the containers in loops extending transverse to the direction. of rotation, each winding head including a winding plate which rests on the yarn mass and is provided. with a slot through which s and an oscillating yarn-laying arn'r for traversing the yarn in said slot.

in practise it is common to install a pluon the line 66, Fig. 3 device in operative o the yarn containers .ralit v' of these winding and twisting units in a frame and to provide a common driving elementi or operating all ot the units. The frame on which these winding and twisting units are supported is indicated gener ly at 1. The yarn containers are indicated at 2 and each is coupled to and driven by a housing 3 which contains'the winding head, the winding plate of which is indicated at l. The construction of the winding head and housing are or may be all as shown in my co-pending application Ser. No. 10,109, filed May 19, 1923, and fortune-part of: my present invention.

'lhe winding heads are all driven from a common driving shaft 5 which extends the length of the frame 1 by any suitable gear connection, such for instance as shown in my co-pending application.

The housing 3 and the container containing the winding head are retained in fixed position on the frame but each yarn container is vertically movable so that it can be raised into operative relation to the winding head as hown at the right in Fig. 4 or may be lowereifl into the position shown at the left in Fig. 1: to permit it to be dis connector and removed from its winding head.

The frame 1 is provided with a platform 6 adapted to receive the yarn containers when they are in their lowered posit-ion and each yarn container is adapted to be rotative ly supported on -a step bearing 7. Each step b -:-a-r1ng 7 is provided with a centering projection 8 adapted to enter-a recess in the bottom of the yarn container and is rot-atably mounted onaplunger 9 which is movable vertically in a cylinder or well 10 formed in the base portion 11 of the frame. W hen the plungers are. in their lowered position as shown at the left in Fi g. 3 the corresponding step bearing 7 is below the platform 6 so that the yarn-container is supported on the platform. hen the plunger is raised shown at the right in Fig. 3 the yarn container supported thereon will be lifted up into operative engagement with its winding head and will be locked to its housing 3 by locking pins 12 all as illustrated and described in my co-pending ap plication Ser. No. 572,441, filed July 3, 1922.

I have provided herein pneumatic means for raising the plungers 9. The lower end of each cylinder 10 has a port 13 leading to a duct '14 whichcommunicates'with a pipe 15 leading to a source ofcompressed air supply said 'pipehaving a three-Way valve 16 therein by which the admission of the compressed -air to the cylinder and its escape therefrom can be governed. The pipe 15 will preferably have communication with all of the ducts 14 so that when the threeway valve 16 is operated compressed air will be admitted simultaneously to all of'the cylinders 10 and thus all of the yarn containers will be simultaneously raised into operative engagement with their housings 3. This end is secured by arranging the pipe 15 so that it will communicate with each one of the ducts 1a. *l i here the cylinders 10 are arranged in tworows as shown the corresponding cvlinders in-cach row may be connected to the same duct 1:") as shown in Fig. 3 and this will involve employing a plurality of ducts -lextending transversely of the frame each of which will be connected to the pipe 1&3.

Means are provided for positioning the yarn containers on the platform in proper the compressed airis admitted to the cylinposition Fig. 0. the back row may then be positioned against ders 10 the rising plunger-s 9 will function properly tov lift the yarn containers into their proper position relative to the winding head. The frame herein shown construct ed to accoi'nmodate two rows of yarn containers. For positioning the yarn containers in one row I employ a plurality of posi- .tioning pins 7% secured to and rising from the platform 6, there being two pins for each yarn container. The pins are properly positioned so that when a yarn container is placed against them, as shown in dotted lines Fig. 2, said yarn container will be in the project-ion 8 thereon will enter the rece.-s of the yarn container. I aiso employ similar pins 17 for positioning the yarn contain-- ers of the other row, but I will preferably make the pins 17 movable so that they can be depressed below the surface of the platform 6. The purpose of this is to enable the pins 1 to be carried out of the way when the yarn containers are being positioned against the pins 'T-ft so that the yarn containers can be placed on the platform (3 and then pushed over the surface of the platform against the pins 74-.

While this depressing movement of the pins 17 may be provided for in a variety of ways I have herein illustrated said pin as mounted in as'haft 18 which can be turned thereby to swing the pins from their operative position shown in full lines F to their inoperative position below the level of the platform as shown in dotted lines.

The central portion of the platform (3 formed by a plate 19 (which is omitted in Fig. and this plate is provided with slots 20 through which the pins 17 ma y pass the shaft 18 is turned.

lVhenthe yarn containers are to be placed on the frame the plungcrs 9 will all be lowcred and the shaft 18 turned so as to carry the positioning pins 17 into the dotted line The yarn containers for the pins 74- after which the shaft 18 may be turned to bring the pins 17 into their operative posit-ion and the yarn containers of the front'row placed in position against the pins 17. lVhen the yarn containers have thus been all properly positioned the valve 16 is opened to admit compressed air to the cylinders 10 thereby raising all the plungers 9 and lifting the yarn containers sinmltaneously into operative engagement with their housings 3.

The shaft 18 may be turned in any suit able way. I have herein shown said shaft as 'ing an arm 21 fast thereon at one end wl ch is connected by a link 22 to an actuatlever pivoted to the front of the frame at urning of the handle 23 will. there fore, operate to turn the shaft 18 and move he pins 1'? from their operative to their inoperative positions and vice versa.

Means are provided herein for locking the plungers 9 in their elevated position. Each plunger is shown as being locked in its elevated position by means of a locking pin 25. These pins are slidably mounted in openings 26 formed in the frame 11 and each plunger 9 is provided with a vertical groove 27 to receive the inner end of the pin. At the bottom of each groove 27 is a radial recess 28 into which the pin may be projected to lock the plunger in its elevated position as shown at the right in Fig. 3. The provision of the slot 27 in which the inner ends of the looking pins operate serves to hold the plungers from turning movement and also serves to guide them in their vertical movement. \Vhen the plungers have been raised by the compressed air as above described as shown at the right in Fig. 3 these locking pins will be forced inwardly. The movement of the locking pins 25 inwardly to bring the ends thereof into the recesses 28 will lock the plungers and before the plungers can be lowcred it will be necessary to withdraw the locking pins as will be obvious.

A construction is hereinfprovided by which all the locking pins may be simultaneously operated. Each locking pin is shown as being pivotally connected at its outer end to one arm 29 of an elbow lever 30 which is pivoted to the frame at 31. The other arm 32 of each elbow lever is connected to a coinmon actuator 33 in the form of a bar extending longitudinally of the frame and slidably mounted thereon. This bar is held in position by guiding studs 34: rising from the frame and operating in slots 35 formed in the bar. The construction is such that movement of the bar 33 in one direction will move the locking pins into operative position and movement of the bar in the opposite direction will withdraw the locking pins. This actuating bar may be given its reciprocating movement in any suitable Way. One convenient construction is that herein shown wherein a vertically-extending operating shaft 36 is provided at the end of the frame which has fast thereto an arm 37 having a pin and slot connection 38 with the actuating bar 33 so that turning movement of the shaft 36 will give the requisite movement to the bar 33. This shaft 36 is provided with a handle 137 by which it may be turned.

I have also provided means herein whereby each locking pin may be actuated separately if desired. The connection between the actuating bar 33 and the various elbow levers 30 is such that when the actuating bar is in one extreme position all the levers will be turned into a position to place the locking pins in their operative positions and when the actuating bar is at the extreme limit of its movement in the other direction the locking pins 25 will all be withdrawn. When, however, the actuating bar is in an intermediate position then eachof the locking pins can be independently actuated. This end is secured in the construction herein shown by making the end 39 of each arm 32 forked and by providing the actuating bar 33 with pins i-O which operate between the arms of the forks 39.

The actuating bar 33 is shown in Fig. 2 in an intermediate position and the locking pins 25 for the two right hand plungers are shown as withdrawn while those for the left hand plungers are in their operative position. If the bar 33 is moved to its extreme position to the left Fig. 2 or into the position shown in Fig. 6, the pins 40 will act on the forked ends 39 of the levers 30 which are connected to the locking pins that are withdrawn as shown at the right end of Fig. 2 and will turn said levers 30 thereby project ing the locking pins inwardly to lock the plungers in their raised position. Then the plungers are all locked and the actuator is at the extreme limit of its movement the When the actuator bar 33 is moved to its extreme limit to the right it acts against the opposite arm of the forked ends 39 and turns the levers 30 thereby withdrawing the looking pins 25 as shown in Fig. 7. When the actuator bar 33 is in either extreme position it operates to hold the locking pins either in looking or unlocking position. YVhen the actuator bar 33 is in an intermediate position, however, as shown in Fig. 2, each locking pin can be independently manipulated.

. It will be observed that the arms of each fork 39 are separated so as to provide a lost motion between the pin 40 and the arms of the fork, and this lost motion is enough to allow sufficient movement of the levers 30 to carry the locking pins 25 from their operative to their inoperative position and vice versa.

The arms 29 of the levers 30 are acted.

upon by means of springs d1 which tend to hold the arms in a position with the locking pins 25 occupying the recesses 28 as shown at the left in Fig. 2 and at the right in Fig. 3.

The arm 32 of each elbow lever is pivotally connected to one end of a toggle device 42, the other end of which is pivoted to the frame at e3. The center joint of this toggle device is connected to a handle 4% by which it may be operated. By pulling each handle 4A out or pushing it in the corresponding lever 30 will be turned about its pivot thereby to project the corresponding locking pin into its operative position or withdraw it therefrom. When the actuator bar 33 is in its intermediate position in the position snown into there it is desired to lower all the yarn contan rs then the actuator bar 33 will be given its complete movement to the right 7, this operating turn al the elbow levers 30 and witl draw ail the locking pins 011 l L w hand it it is desired to unlock the plunger of some particular yarn container or yarn. containers then the actuator will be moved into its intermediate position shown in Fig. 2 as er which the handle corresponding to the yarn container which is to be itinloclted will be pushed inwardly thereby swinging the correspoi'idiiigg elbow lever 30 into aposition to withdraw its lochingz pin 25 from the notch 28 of the plunger. 'llhe movement of the actuator bar 38 from its position (3 to the intersne. rte position shown in does not of itself ii'ithdraw any of the locking pins be cause this n'ioven'ient is simply equal to the lost motion between the pins at) an d the forks 212) and during this movement the pins 40 will niere be carried from one side to the ther ot the forks. The springs ll serve to retain the locking pins 25in their operative position at this time and until the levers 80 are aositively moved either by a further movement of the actuator bar 33 or by one of the handles 44;.

l have also provided an interlocking connection between the actuator bar 33 and the means tor driving the shaft by which the shaft cannot be started until the locking bar it; is in the position shown in F 7 and all of the plungcrs are locked in their ele ra ed position; and by which the locking; nie ot be withdrawn to unlock any plun ger until after the controlling mechan' .or operating the shaft 5 is rendered inoperative. The shaft 5 may be driven in any suitable way and any desirable control .i'nechs-inisin for starting or stopping it. I have herein illustrated the shaft as actuated from a dr ing belt 45 which is adapted to be shitted from a pulley 4M5 loosely mount ed on the shaft 5 to a pulley 4:? "law thereon.

'ihe belt 4-1 is eluted tron'i one pulley to the other by a belt sh which is shown id of a swinging arm 49 50. Tl is belt shipper can be aca shipper rod 51 that extends the the frame.

e interio v :ing connection above dee as carried on the e pivotec 1 mew/'29 belt shipper arm 49 and extending laterally therefrom and a co-operating arm fast on the shatt 36 and extending laterally t .erel rom. It will be noted that the movement of the arm 52 is in a vertical direction whilethat oi the arm 53 is in a horizontal tliIGCLlQll. i

The arm 53 is arranged beneath the arm and the parts are so desi 'ned that When the belt is on the loose pulley as shown in Fig. 9 the arm 52 will be raised above the arm so that the shaft may be turned freely. ldurtliermore when the belt shipper is in this position and the shaft 36 is turned to t. m the actuator bar 33 either into the position shown in Fig. "7 thereb'y'to unlock all oil the plungers tl'lor into the intermediate position shown inFig'. 2, saidarmbil will stand beneath' the arm 52 and Will thus prevent movement of the belt shipper. W'hen, however, the shaft-36 is turned to carry the actuator bar into the position shown in Fig. '6 thereby looking all of the plungers raised then the arm 53 is lt'ree from the arm 52 and the belt shipper can 'be iioved into the'positionshow'n in Fig.8. T iis arm 52 formed with a, shoulder 54 which engages the arm whentlie' parts are in the position shown in Figs. 8 and 10. When theparts are in' .thisposition the shoulder o l locks the arm from moyement and therefore so long as .the belt is on the tast pulley the shaft 36 is locked andL cannot be turnezil to unlock the pluiigers Hence before a y piimger"centennlocked it is necessary to shift the belt onto the loose pulley thereby br' iging the inachine to rest."
